To all whom it may concern:

Be it known that I, SoLoMoN H. GOLDBERG,

' of the city of-Chicago, in the county of Cook and State of Illinois, have invented certaln.

new and useful Improvements in Mechanism for Producing Roofing Material, of which the following is a specification.

My invention relates to mechanism for producing roofing material, and more articular-1y tomechamsm adapted to pro uce a roofing materlal having designs upon one of its surfaces, and is a divisional applica tion of my original application No. 738,612, filed"December 26th, 1912. This original application relates particularly to a roofing and' a process for producing such roofing material in the form of lengths of backing material such as "paper or felt treated or sat- -urated with asphaltic compounds or other material and to one of-whose surfaces gravel, grit. sand or other comminuted or granular surfacing material is applied.

. In roofing material of the type mentioned pressing operation, and it is one of the salient objects of the invention to provide a simplified means for producing such ornamental effect whereby large quantities of the ornamented roofincg-can be rapidly and economically produce My improved mechanism is adapted to apply continuous pattern lengths to roofing material backing lengths on which one surface is made adhesive so that the pattern lengths will cling to the backing lengths and arrange themselves smoothly thereon. After application of the pattern lengths, the backing lengths receive an applicatlon of gravel or other granular or comminuted material which material will cling and adhere to the adhesive areas but will not adhere to the intermediate areas or lines formed by the pattern. After'the loose surfacing material is removed from the pattern lines, the finished stockhas a wear surface which gives the appearance of shingling or tiling, the

pattern lines representing the outlines of shingles or tiling or any other desired ornamental use.

In my pending application, Serial No. 736,611, filed December 26th, 1912, I have disclosed an apparatus for cutting pattern lengths andfor protecting the pattern lengths thus cut, it being practically impossible to apply the delicate pattern lengths by hand to the roofing material backing length or to apply it directly from the roll. The delicate pattern lengths are therefore wound up on a roll with a length of backing material, which rolls are applied to deliver the pattern length to the roofing material backing length in such manner that the backing material will retain control of the pattern length practically up to the time of its application to the backing length in order that smooth and ac curate application of the pattern lengths will result.

My invention further relates to the mechanism for feeding these pattern lengths from the backing lengths into smooth, accurate and intimate engagement with the roofing material backing lengths.

Other objects of the invention are to pro vide an improved means for producing a roofing by the process disclosed in my original application above referred to; to provide an improved mechanism for feeding the pattern lengths to the traveling roofing back-' ing mater1al; to permit of the uniform feed ing of the roofing material to receive its facing of granulated or comminuted material; to prevent distortion and tearing of the delicate pattern and to insure its accurate and uniform application to the roofing stock; and ,in general to provide an improved mechanism for producing roofing having designs applied to one surface thereof.

The invention further resides in various features of construction and combinations of arts described and shown in the accompanymg drawings in which Figure l is a more or less diagrammatical layout, in vertical section, of the improved apparatus.

Fig. 2 is an enlarged front elevational view of the pattern roll supporting mechanism and the adjusting mechanism for con-' trolling the feed of the pattern lengths.

Fig. 3 is a side elevational view of the mechanism of Fig. 2.

Fig. 5 is a plan view of a section of finished roofing product, and

Fig. 6 is a section taken on plane 6-6, Fig. 5.

Referring to Fig. 1, 10 and 11 represent upper and lower rolls, the upper roll being driven in a suitable manner as by belt 12 driven from shaft 13. The body or backing 14 of the roofing material is propelled through these rollers and has a suitable coating applied thereto to cause its upper surface to be adhesive in order to receive the pattern lengths. Accordingly, a tank 15 is mounted in a suitable manner above the upper roll and in which asphaltuim or other suitable material is heated, as by means of steam coil 16, the spout 17 delivering the heated material to the roofing backing 14, this material being distributed evenly and uniformly across the backing 14 by the upper roll 10. ()n a suitable structure 18 is mounted a hopper 19 for delivering gravel, grit, sand, or other surfacing material to the backing 14. Between the outlet of the hopper and the roll 10 the supporting mechanism for the pattern lengths is positioned, this mechanism being represented as a whole F. In this mechanism a roll 20 on which a pattern length 2 is wound, is adapted to be driven to unroll the pattern so that it may travel with the roofing backing 14. \Vhere shingle or tile effect is desired to be produced, the patterns consist of interconnected lines or ribbons of thin stock, such as paper, as clearly illus trated in Fig. 4. The pattern, upon reaching the traveling backing 14, adheres to the sticky surface thereof and by gravity will arrange itself and adhere to the backing and will then present a smooth, non-adhesive surface'or lines representative of shingles, tiles or the like, and to which surfacing material will not adhere. Therefore, when the backing together with the pattern superposed therein receives gravel or other surfacing material from the hopper 19, it will retain the surfacing material only at the sticky areas and the gravel deposited on the pattern lines will fall off or can be readily brushed off. Preferably, however, the backing 14 with its charge of coating material is given a reverse bend about the upper and lower rollers 21 and 22 in order that the loose surfacing material may drop therefrom into a receptacle 23 from which it is conveyed away as by means of a screw 24. The surfacing material is also preferably forced more intimately into engagement with the sticky areas and after passage about rolls 21 and 22 the roofing stock may pass about rollers 25 and 26 and between the compression rollers 27 and 28.

It may also be desirable to face the lower side of the roofing backing for strengthening purposes. For this purpose a support 29 is provided for pivoting a supply roll 30 of facing material 31, such as burlap, this burlap passing between the rolls 10 and 11 and below 'the backing 14 to be pressed against the backing. In order to cause the facing to adhere to the backing, the lower roll 11 may dip into a pan 32 containing material such as asphaltu-m which may be heated as by means of steam coils. 33. As the rolls 1.0 and 1 1 are now rotated, the asphaltum or other material is spread over the top of the backing 14 and the material from pan 32 is carried up by roller 11 and squeezed through the porous burlap and against the bottom of the backing, the burlap being thus caused to adhere firmly and smoothly to the backing and being saturated at the same time with material from pan 7 Before the backing, with the facing and pattern applied thereto, reaches the dumping rolls and compression rolls, the asphaltum or other material applied thereto should be sufficiently cool so as not to stick to the rolls. To assure that the plastic coating will not stick to these rolls, a rotary dusting brush 34 may be mounted below the roofing stock as it comes from the gravel hopper, suitable dust or powder being fed to the brush from pan 35 which is replenished by means of a conveyer belt 36. If necessary, the top of the roofing stock may also be powdered or dusted and to this end a chute or duct 37 is provided for delivering powder or dust. Upon passage of the material about the dumping rolls, the surplus powder Will be thrown off so that after the material emerges from the pressure rolls 27 and 28 all interposed sticky surf-aces will have been powdered. ()f course, instead of powder or dust, other material such as grit or sand may be applied to cover the sticky interposed surfaces. The appearance of the finished product is clearly represented in Fig. 5 and also in Fig. 6.

The mechanism for controlling accurately the feeding of the patterns, is shown in detail in Figs. 2 and 3. A beam 38 supports hangers 39 in which-is journa-led a shaft 40, this shaft supporting a pulley 41 driven by belt 41 from the main drive shaft 13. Secured to and extending downwardly from bearing frames 42 and 42 on shaft 40 is a supporting structure comprising side frames 43 and 43. At the bottom these side frames support bearing brackets 44 and 44 for jourorder that the empty roll may be removed and a fresh one applied, and to prevent endwise play of the shaft an annular groove 47' thereln is engaged by a plate 48 secured to the bracket side. Above the brackets 44 and 44' other brackets 49 and 49 support a shaft 50 for mounting a take-up roll 51 for taking up the backing material b. In the co-pending application referred to is described the manner in which pattern lengths are wound up on rolls each with a stri of backin material, and it is these filled rolls whic are applied to the shaft, the rolls being adapted to be slid off and to be secured thereto as by a set screw 46. The rolls 51, after winding thereon of the backing material from one of the rolls 46, become the feed rolls in the machinery described in the co-pending application referred to and the backing material thereon is fed to the take-up rolls to be used over again in connection with other pattern lengths.

The shaft 50 supporting the take-up rolls 51, supports at one end the gear 52 meshing with the transmission gear 53 supported from the shaft 43 and which is driven by a gear 54 on shaft 40. The supporting frame for the rolls is bodily shiftable along shaft 40 and the gear 54 is sufficiently wide so as to mesh at all times with the transmission gear 53. The backing band 5 acts as a belt for driving the roll 46 which delivers to the roofing backing 14 the pattern lengths. The pattern should of course travel atall times at the same speed as the backing in order that it may accurately and smoothly adhere thereto. A friction wheel 55 is secured to theshaft 50 and is engaged by a friction band 56 secured at one end to a bracket 57 and at its other end looping about 'a disk 58 eccentrically mounted on a stub shaft 59 extending from frame part 42'. A grip frame 60 is secured to the disk so that it may be rotated to adjust the frictional engagement of the band with the wheel, clamping of the wheel 55 resulting in more or less slip of the driving belt 42. By means of a handle 60 the supporting frame structure may also be readily moved bodily along the shaft 40.

The details of operation of the pattern feeding mechanism can be clearly understood from the above description. When a filled roll 46 is applied to'shaft 45 the end of the backing to the in-take roll 51 and the end of the pattern length p is applied to the roofing backing 14. By shifting the pattern roll supporting structure back and forth along shaft 40 and by operating the brake mechanism, the pattern can be caused to accurately and smoothly adhere to the adhesive surface of the backing without being subjected to strain of any kind, the pattern being fed fast enough that it Wlll at all times be slightly slack that it may be free to fall by gravity into proper position on the backing. It will be noted that the pattern supply roll 46 is close to the roofing acking so that the guiding and smoothing effect of the backing material is maintained practically up to the time that the pattern engages with the backing. After one pattern length is unrolled, a fresh roll is ap plied to shaft 45 and the filled roll 51 is transferred to another machine to be wound up on an in-take roll together with another pattern length. l

Fig. 5 shows one design of finished roofing product, the uncovered pattern ribbons outlining the covered sections which are representative of shingles or tiles.

By means of my improved apparatus, surfacing can be very quickly and efliciently applied to roofing backing in any desired design, and the accurate application of the pattern to the backing will cause the designs to be accurate and symmetrical.

While I have shown and above described an apparatus capable of producing the roofing and carrying out the process defined in my original application, I do not desire to limit my invention to the particular embodiment shown.
